Hi.
I have recently purchased an Arduino Mosfet IRF520 that is rated for 1A, but I plan on running approximately 2.5A on it(will install heatsink!).
Are they safe to operate for days? I plan on using it in an Escape Room to dim 4 x 2-3W 12VDC light bulbs. The program I've designed with dim the lights on random occations, but mostly will have it fully on.
It works right now, but is making a humming noise while dimming. I've heard it might be due to some EM-field. It does not get hot at all.
If not advisable, do you have any other ideas for other products that might work for me for this rather specific purpose?
Have a great day!
